i specificatidniof Letters Patent. Patented Al lg. 17, 1915.

Applicatioii'fild February 24, 1915. Serial No. 10,187.

To all whom it mag concern 1 Y Be itknown thatI, J oHN-H. BRAMKAMP. a citizen of the United'States, residing at Portland, in the county of Multnomah and State of Oregon, have inventedla. new and useful Improvement in, Roundabouts, of

' which'the following is a specification, reference being had to the accompanying drawngs. a

My invention relates to roundabouts or moving amusement apparatus having seats, swings, cars or other novel means for riding.

The object of my invention-is to provide an amusement apparatus. similar to that de scribed in Letters Patent No} 9.53,119 ,here-v 'tofore issued to me on March'29,1910, for an improvement in roundabouts, and particularly for mprovements u scribed in said patent.

I now propose to provide the device with a peculiarly arranged track upon the table,

for cars to travel upon, also to provide a motor car for operating the table or. platform, which shall. travel upoir the latter.

. I attain these objects, as well as other distinct advantages, by the mechanism, "construction and arrangement of parts illustrated in the accompanyingdrawings, which form a part hereof. a a

Figure 1 is a plan view of the table or platform of the device showing arrangement of the car tracksthereon. and starting position of cars. Fig. 2 is a sectional elevation view of a track crossing safety guide. Fig. 6 1s a sectional elevation of a'track crosslng guide and car guide T-rail on line 66 of Fig. 5. Fig. 7 is a plan view of the car guide rail.

Like letters or numerals refer to like parts throughout the views.

' A is a socket secured to the earth. 7

B is a shaft, having an integral rounded lower end 8, adapted to rotate in the socket A in an inclined position.

C isa circular table or platform, the center of which is secured upon the upper end of the shaft B. The table is rigidly secured upon the shaft by means of the system of stay braces D.

pen the devicedethe shaft B which will allow the rim of the table to roll thereon. a

A circular track 9 is placed upon the out,- ermost surfaceof the table C.

An outside continuous uard railing 10 is provided on the edge of the table.

A car 11- provided with power means to drive it is placed upon the track 9. The carlll is also provided with guide rollers 12 which engage the guard railing 10.

Within the outer track 9 is asecond track 13, upon the surface of the table C. This track is circular and'parallel with the track 9 to a certain division 14 thereof. At the division, the track 13 extends inwardly of throughout the length of said track except at the crossings. For convenience of illustration therailing 16 is omitted in Fig. 1 and also in the upper half of Fig. 2, but it is understood that it extends along the tracks to each crossing where it stops in order to permit the cars to pass over each crossing and through the guard rail.

Upon the track 13 are placedt raveling cars 17 18 19. These cars I are provided with guide rollers 20 which engagethe outer railing 16. All cars are shown in starting position for the direction of the arrows.

Upon the surface of the table at-and within'the intersections of the track 13 are placed transverse guides 22 having slots 23. See

Figs. 5 -6. The guides are rounded at the outside entrances as shown to facilitate the sliding engagement of the guide rail therein. A crossing car guide T-rail 24: is rigidly secured upon the lower surfaceof the cars 171819. One of these cars 17 is illustrated in Fig. 4 with a guidethereon. The guide rail 24 is positioned and arranged longitudinally of the car and is pointed ateach end, and is thus adapted to enter and pass through the slots 23 and slidably engage the guides 22 as the car moves over the track crossing.

It will now be seen that when my device is erected in operative position, as illustrated bythe imparted motion of the table, from their standing position, in the direction of the arrows before them along the length of T the track 13. It will be observed thatthe carsa're all started from the samef radius oifthe table and thereupon the car 17 having alo'wer grade to ascendjon' the moving table. will acquire immediately higher speed than the others jandfwill precede them in reaching the succeeding crossings infrespecdijfl'erjs in certain respects from my previous tive order until it emerges againin to the outerpart ofthe track f'lhe same rule applies'to" cars18v and 19 respectively, each in, 7 turn becoming the outer car17. This causes theffcars to have the appearance.- of racing with each other on parallel tracks,"but by.

reason of the arrangement-of'the track 13 and predetermined starting positions, the cars never meet at the same crossing.

i'lhe car guide rails and the crossing guidesare provided to in sure safety of passengers; The car rollers" and-guard rails are also provide di or the same reason.

It willbe notedthat' my present device one,;illustrated'injthe Letters Patent hereinbefore rie ferred tol Italso diiiers from anotherapplication for similar Letters Pat 7 ent, Ser. No. 838,336, filed May 13, 1914:, and;
